As modern vehicles become more and more electronic, automotive bus systems are becoming more and more complex. Automotive bus testing is an important task that helps to identify problems in vehicle electronic systems and to guarantee the safety and reliability of vehicles. In this paper, we will introduce five common automotive bus systems and the related test tools.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Controller Area Network (CAN) is a data communication bus commonly used in modern automobiles, CAN bus is a high-speed bus that supports many different data transfer rates and can be used to transfer data from various vehicle systems, such as engine, transmission system, vehicle stability control system and anti-theft system.CAN bus test tools monitor the data transmission in the CAN bus and detect any problems and errors in the bus.
